9 Claims.

This invention relates to improvements in shaker conveyers and has as its principal object to provide a swivel connection in a shaker conveyer pan line permitting universal pivotal movement of one pan with respect to the next adjacent pan which connection is particularly adapted for use with a feeder head for accommodating said feeder head to uneven bottoms and pitching seams.

Other objects of my invention will appear from time to time as the following specification proceeds My invention may be more clearly understood with reference to the accompanying drawings 1-5 wherein:

Figure 1 is a top plan view of a conveyer pan line embodying my invention with parts broken away;

Figure 2 is a side elevation of the apparatus shown in Figure 1;

Figure 3 is an enlarged detail plan view of the swivel connection shown in Figure 1;

Figure 4 is a side elevation of the device shown in Figure 3 with certain parts shown in longitudinal section; and I Figure 5 is a sectional view taken substantial- 1y along line 5-5 of Figure 4.

In the drawings the embodiment of my invention illustrated includes a reciprocatory shaker 30 conveyer pan line including a trough section I!) driven in the usual manner, not shown. The trough section It) has a horizontal swivel section, generally indicated by reference character I i, detachably secured'to the forward end thereto the forward end of said swivel section and a feeder head 53 is secured to the forward end of said p-an l2 for reciprocable movement with all of the parts named. The feeder head l3 may be of a usual construction and operation well known to those skilled in the art and is adapted to carry an extensible pan Hi having a shovel l5 formed integral with its forward end for picking up material fordischarge into the extension pan I2. 45 As herein shown, the extensible pan I4 is provided with plates it, it extending along each side thereof, which plates are adapted to be selectively engaged by means of grip blocks H, I! carried on carrier members l8, 18. Operating levers l9, l9 are provided for engaging the grip blocks I1, I!

with'the plates 16, IS in the usual manner at certain portions of, the forward or return stroke of theshaker conveyer, through a suitable system of levers, which will not herein be described since 55 it isno portion of my present invention.

5 of. An extension pan i2 is detachably secured With reference now in particular to the details of the swivel section II and several of the novel features of my invention, the latter includes a relatively short flaring trough section 22 connected to the main trough section In by'a usual 5 detachable means, herein consisting of a pair of bolts 24, 24 extending through eyes 2|, 2| depending and extending laterally from the-bottom of said trough section 22, and similar eyes 20, 20 formed on the main trough section l0. A shoe 10 23 adapted to rest on and slide along the mine bottom has an upstanding support 26 secured thereto, which is interposed between the trough l0 and trough section 22 and has apertures registering with the eyes 20 and 2! of said trough 1.5 sections.

The rear portion'of the trough section 22 is nested within the forward end of the trough l0, and its forward flared end is of a substantial width to permit another troughsection 25 to 20- overlap said flared end and discharge material therein when the adjoining troughs are pivotally moved at various angles with respect to each other.

The swivel connection includes a reinforcing 25 plate 21, secured to the under side of the trough section 22 and provided with a bored portion 28 adapted to receive a lug extending upwardly from a bearing boss 29, which bearing boss is secured to the under face of the reinforcing plate 21 in 30 any suitable manner, as by rivets 30, 30 (see Figure 4) An annular member 3| is journaled on the bearing boss 29 and its upper surface abuts the under surface of the reinforcing plate 21.

A retaining plate 33 having an annular flange 34 35 extending upwardly therefrom is provided for holding the member 3| in position on the bearing boss 29 and permitting said member to be pivotally moved with respect to said bearing boss. The outer periphery of the annular flange 34 also serves as a bearing member for a link member 35 and the portion of the retaining ring 33 extending outwardly beyond said annular flange,

is adapted to abut the under side of said link member. The retaining member 33 is herein shown as being secured to the under side of the bearing boss 29 by means of capscrews 36, 36 in a suitable manner. Thus, the member 3! and link member 35 are adapted to be pivotally moved with respect tothe trough section 22 about an 5 axis extending perpendicularly to the bottom surface thereof.

A connecting bar 31, commonly referred to as a pendulum,.is adapted to be pivotally connected to the outer end of link member 35. The pendulum 31 is also pivotally secured to a jack 39,

which may be interposed between the mine roof and mine bottom in such a manner that said pendulum holds the trough l0 and trough section 22 from lateral movement with respect to the ground, but permits the usual reciprocable action of the main pan line, as well as lateral rocking movement of the pan line, as will further appear.

The member 3| has a forward extension to which a member 40 is pivotally connected by means of a pin 4| horizontally disposed to support the member 45 for pivotal movement with respect to the member 3! in a vertical plane. 7 The member 40 has a spindle or shaft 43 formed integral therewith and extending forwardly into a longitudinally bored portion of a member 44 secured to and depending from the forward trough section 25 and so arranged as to support the rearward end of said forward trough section above the rearward trough section 22, a distance sufiicient to permit free pivotal movement of said sections with respect to each other in a vertical plane. A nut 45 is threaded on. the end of the shaft 43 for retaining said shaft in member 44.

It is thus apparent that the trough sections 25 and 22 may have limited universal movement with respect to each other, since they have pivotal movement on a vertical axis disposed rearwardly of the forward end of the trough section 22, about an axis extending transversely of said trough section 25 disposed adjacent the forward end of said trough section 22, and about an axis extending longitudinally of said trough section 25 disposed forwardly of the forward end of said trough section 22. Thus, the trough sections 22 and 25 may be disposed in various angular relations with respect to each other for the discharge of material from the forward into the rearward trough section in all conceivable positions of adjustment of said trough sections with respect to each other and permitting the pan line to accommodate itself to irregular mine bottoms as well as to permit the trough section to be pivoted with respect to each other for conveying material around corners where desired.

It may also be desirable to provide a sliding support 48 for the pan line in advance of the universal connection just described. For this purpose a pair of elongated eyes 46, 46 depend and extend laterally from the bottom of the forward trough section 25 and are adapted toregister with suitable apertures formed in a flange 41 extending upwardly from a ground engaging shoe 48 and elongated eyes 49, 49 depending from and extending laterally from the bottom of the extension pan I 2 and abutting the forward end. of said flange so that suitable connecting bolts 50, 50 may connect said extension pan and shoe to said forward trough section in a usual manner.

It may now be seen that a universal swivel connection of a novel, efficient and simple construction has been provided for a shaker conveyer pan line, to permit the pan line to accommodate itself to uneven bottoms and scams pitching in various relationships with respect to each other. Said swivel is particularly adapted for use with a feeding head of the type described for permitting a shovel carried by said feeding head to gather material for discharge into the main pan line where the seams are pitching or the bottom is irregular and it will further be seen thatemy invention accordingly permits the use of a feeding head and shaker conveyer in more places than formerly and improves the operation of shaker conveyers, especially where bottom conditions are irregular and where top conditions are such that numerous props are necessary and many turns in the pan line are necessary to avoid the props supporting the roof, it being understood that more than one swivel may be used under such conditions.

While I have herein shown and described one form in which my invention may be embodied, it will be understood that the construction and arrangement of the various parts may be changed or altered without departing from the spirit or scope thereof. Furthermore, I do not wish to be construed as limiting myself to the precise construction illustrated, excepting as it may be limited in the appended'claims.
